Had the jensen running...now won't start. I charged the battery up so it is fully charged but when I turn it over it seems like the batttery is almost dead as it turns over really slowly and of course does not start.

Is it possible that the battery might be done even though my charger says it is fully charged??

Remove the battery terminals and posts & clean them up with some 400 grit paper. Some dielectric grease won't do any harm here. Do the same to the earth lead to the body & check/clean up the starter terminals. When a battery goes bad it won't hold much of a charge and the acid becomes as much use as water. Even if it is the battery it won't break the bank.

Thanks...I'm going down that list. I managed to get a new battery...I did look at the alternator today and the connections seem to go back to the solenoid. I have to take all the tape off the wires and see exactly where they go and obviously clean off the connections.

Well if you have a new battery and it is fully charged, does the engine now turn over faster. I dont think you have a starter issue or it would not turn the engine over at all. As mentioned you could have a alternator problem if the new battery keeps losing charge, what does the gauge show your charge rate at.

The real biggy for most electrical problems are as stated, dirty and bad connections.
